Short answers, pulled from the story.
The Battle of Yellow Tavern was fought on the 11th of May, 1864, at an abandoned inn six miles north of Richmond, Virginia. The site sits at the intersection of Mountain Road, Brook Road, and Telegraph Road.
Confederate Maj. Gen. J.E.B. Stuart was mortally wounded at Yellow Tavern and died in Richmond the following day. He was shot by Union private John A. Huff, a forty-four-year-old former sharpshooter, using a .44-caliber revolver from a distance of ten to thirty yards.
Union Maj. Gen. Philip Sheridan commanded over 10,000 troopers and 32 artillery pieces for the broader raid. At Yellow Tavern itself, Sheridan's force outnumbered Stuart's 4,500 Confederate troopers by three divisions to two brigades.
Sheridan's raid had three goals: defeat Jeb Stuart, disrupt Confederate supply lines by destroying railroad tracks and supplies, and threaten Richmond to distract Robert E. Lee. The raid was authorized by Lt. Gen. Ulysses S. Grant after Sheridan argued his Cavalry Corps should operate as an independent offensive force.
Union forces suffered 625 casualties at Yellow Tavern. Sheridan's men captured 300 Confederate prisoners and recovered almost 400 Union soldiers who had previously been taken prisoner.
On the evening of the 9th of May, Sheridan's column reached the Confederate supply base at Beaver Dam Station. His men destroyed railroad cars, six Virginia Central Railroad locomotives, and telegraph wires, and freed almost 400 Union prisoners captured at the Battle of the Wilderness.
